, BATTERY TERMINAL CONNECTER.

Application filed February 3, 1928. Serial- No. 251,689.

allowing acid resisting material to be placed in the chamber, forinstanoe hard oil, which will prevent sticking of the bolt.

A further object is to provide the plug -with a chamber into which anelectric conductor is received, thereby utilizing the plug as aconnecter.

With the above and other objects in view the invention resides in thecombination and arrangement of parts ashereinafter set forth, shown inthe drawing, described and claimed,

it being understood that changes in the precise.

embodiment of the invention maybe made within the scope of what isclaimed without departingfrom the spirit of the invention.

In the drawing: Figure 1' is a horizontal sectional view through theconnecter.

Figure 2 is a side elevation of the connector. Referring to the drawingthe numeral 1 designates a contractible sleeve adapted to encircle abattery terminal 2, and to be contracted into close bindingengagementwith the periphery of the terminal. One sideof the sleeve 1 has formedintegral therewith a body member 3 having a chamber 4 therein, and whichchamber 4 is adapted to receive hard oil or other material which willprevent corrosion around the head' 5 ofthe bolt 6 for preventingsticking of the bolt for instance so the sleeve can not be expanded orcontracted. The bolt 6 extends through an enlarged aperture 7 in thebody member and is threaded at 8 through the arm 9 of the sleeve'l,therefore it will be seen when a tool is placed on the head 10 of thebolt the arm 9 maybe forced toward the body 1 for contracting the sleeveor away from the body 3 for expanding the sleeve, consequently stickingincident to corrosion of the bolt at its headed end 5 is obviated. Theheadr5 also forms a closure for the inner end of the aperture 7, therebypreventing loss of material therefrom. The I head 5 may be placed on thebolt 6 in any suitable manner after the bolt is in position and throughthe open threaded end 11 of the body member-3, and applicant does notlimit himself in this respect.

Threaded into the threaded end 11 of the body member 3 is a plug12,which forms a closure for the chamber 4 and also serves as' anadditional function asa socket 13 for a conductor wire 14, therefore itwill beseen it will only be necessary to provide the socket 13 in theplug 12, which is a relatively simple operation. When it is desired toreplace material in the chamber 4, it will only be necessary to unscrewthe plug 12, which will alldw ready access to the chamber and to theheaded member, and it will also be noted that where there is anytendency to stick, by having the aperture 7 larger than the outsidediameter of the threads of the bolt 6, any sticking or jamming can beeasily broken by tapping on the bolt head 10.

From the above it will be seen that a battery terminal connecter isprovided, which is simple in construction, provided with a chamberforthe reception of corrosion'resisting material, and the closure plug forthe chamber is utilized as-a socket for the reception of a conductorwire, which may be secured therein in any suitable manner, for instanceby soldering.

The invention having been set forth what is claimed as new and usefulis 1. A battery terminal connecter comprising a contractible sleeve, abolt for contracting said sleeve, a body member having achamber thereinfor the reception of an antioorro ing material, a head carriedby saidbolt, said bolt extending through an aperture in the body member andsaid head disposed within the chamber, a closure plug threaded in thebody member, and means whereby a conductor may be attached to'saidclosure plug.

. axial alinement with the bolt and a conductor receiving socket in saidplug.

3. A battery terminal connecter compr sing a body member having achamber there-- in, a contractible sleeve carried by said body member,an arm carried by said contractible sleeve, a bolt threaded through saidarm and 10 etxending into the chamber of the body member, ahead carriedby said bolt in said chamber and a combined plug and connecter socketthreaded in said chamber.

Intestimony whereof I hereunto affix my 15 signature.

JOHN BONE.
